Model 4900A Pneumatic Volume Booster
Brand: Fairchild Industrial ProductsRotork Fairchild’s M4900A is a High Flow Pneumatic Volume Booster designed for high precision applications.
With its Cv of 9 in both forward and exhaust modes, this pilot operated booster provides fast response, very low deadband and high precision control.
In its pilot operated regulator design, the M4900A handles up 250 psig, [17.0 BAR], (1,700 kPa) supply pressure and delivers an output pressure up to 150 psig [10.0 BAR] (1,000 kPa).
The Fairchild Model 4900A Booster provides a flow capacity of 500 SCFM (850 m3/Hr), which equates to a Cv factor of approximately 9 in both forward and exhaust modes.
Features- Cv = 9; Flow capacity of 500 SCFM (850 m3/Hr)
- Ratio Accuracy of 0.5%
- Very low deadband between the operation of the supply valve and exhaust valve
- High capacity exhaust valve
- Large area diaphragms
- Soft seat supply and exhaust valves
- Pressure balanced supply valve
- Damped diaphragm control chamber
- Two accessory ports connected to the outlet chamber
- Tapped exhaust port
